The purpose of this study is to get an overview of project-based learning in the habit of creative thinking of teacher and students perspective of mathematics. This research included development research with qualitative descriptive analysis. The study follows the stages of identification, development, and dissemination (Borg & Gall). The trial was conducted in the sixth semester of Mathematics education program at STKIP Taman Siswa Bima. Data collection used observation sheet, in-depth interview and test. Learning device through development stage, after validation test and test can be said practically with the existence of validator assessment which stated device valid and can be used after the revised, the result of observation of learning implementation every Teaching Events Unit on a good criterion, the result of observation of students' learning in every Teaching Events Unit show active participation. Learning devices are said to be effective in the presence of students respond positively to learning each Teaching Events Unit, Student Duty Plan and test result learning instruments meet the criteria of valid, reliable and sensitive as well as completeness of classical learning fulfilled.
